How to verify if an IPV6 address entered in a textbox is valid ?

Hi,
How to verify if an IPV6 address entered in a text box is valid. I have a swing application. Until now we used only IPV4 address and we had a gui component with only four entries, which checked if the number entered is <= 255, so the user had to enter a correct address. Now with IPV6 there are IPV6 addresses, IPV4 mapped addresses, IPV6 zero compressed addresses and leading zeroes dropped kinds. We cannot supply a fix gui component.
So if I provide a textcomponent which accepts strings - how do i check if the ip addresses entered by the user is valid. Can I use INET6Address to do this ? is there a way ?
Thanks.

InetAddress.getByName(String host)
If it returns an Inet6Address without throwing an exception, I guess that would work.

How to Test if an Email Address Exists?

So we have all been doing email address validation for awhile which I know how to do, but validation only tests if an email address is entered in the right format. It doesn't verify if an email address actually exists. I am creating an application where there will be membership fees, and so an email has to be in more than the right format, I must be positive that it actually exists when the account is created before any money changes hands. This is critical. Unfortunately, all of my searching for this relating to Flex or Flash Builder has yielded no results. Does anyone know of any tutorials or blogs or articles that discuss how to test if an email address entered by a user actually exists using Flex? or does anyone here have any suggestions on how to approach this problem?
Thanks!

The only definitive way is to send the user an e-mail, and have them verify the email address.
In the past I remember researching options. Depending on how mail servers were set up; I thought there was some way to ping a mail server and ask if the e-mail address was valid. This functionality was turned off on most mail servers to prevent spammers from harvesting email addresses.
Here are some good info on the general approach:

Convert IPv6 address to decimal

How do we convert an IPv6 address to its decimal equivalent using java?
I could find different tools on Internet but not the java code for the same.
Any help would be much appreciated.
Thanks.

Hello EJP
Please visit the following URL:
https://www.ultratools.com/tools/decimalCalcResult?ipAddress=805b%3A2d9d%3Adc28%3A0000%3A0000%3Afc57%3Ad4c8%3A1fff
This converts the IPv6 address (which is in hexadecimal format) to a decimal number.
I need to implement this functionality. I could not find any method in java.net.Inet6Address class for this.
To convert an IPv4 address which is in String format to its decimal equivalent, we can use following method:
<code>
long stringToLong(String ipAddress) {
          String[] octets = ipAddress.split("\\.");
          long intValue = 0;
          long currentOctet;
          for (int i = 0; i < octets.length; i++) {
               currentOctet = new Integer(octets[(octets.length-1)-i]).intValue();
               intValue = (currentOctet << i*8) | intValue;
          return intValue;
</code>

Enter-PSSession does not work when a IPV6 address is entered as the -Computer value.

I cannot get Enter-PSSession to work with a specific IPV6 address and when TrustedHosts is also set to this address.
NOTE: If TrustedHosts is set to "*", then the command succeeds, so I'm pretty sure the target is configured correctly to allow remote access.
Example:
set-item wsman:\localhost\Client\TrustedHosts "fc00:10:114:247:2d0b:6bf8:c982:ce10"

How to verify primary email
http://support.apple.com/kb/he68

Icloud will not back up because it says email address not verified. I am not getting a link in my email to follow to verify account, checked email address listed is correct, so how do I verify email address when I dont get the email link?

I am unable to verify email address to sign in to icloud so that I can backup my stuff. I am not getting an email from apple to follow a link to verify email address. I have checked to make sure the email address is correct in the icloud settings, but all it will tell me is to check my email for instructions on how to verify my account. I am not getting the email! Please help, I am able to sign in to my itunes account and buy new music all the time! I get my itunes receipts and everything, and know the email is correct so what is the deal?

If you have given correct info about you ios 6.1.3 - all you need to do is delete account. You will be able to sign in with new one afterwards. Make sure you don't delete any info when you see those prompts.

I have verified my new email address as my Apple ID but my IOS devices keep asking me to sign in to my previous email/Apple ID but have no access to it. How can I stop or change this?

I have verified my new email address as my Apple ID but my IOS devices keep asking me to sign in to my previous email/Apple ID but have no access to it. How can I stop or change this?

To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iDevice, then sign back in with the ID you wish to use. When you do this you may find that the password for your old ID isn't accepted. If this should happen, and if your old ID is an earlier version of your current ID, you need to temporarily recreate your old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. You can now use your current password to turn off Find My iDevice on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

How to verify VPLS mac-address forwarding

Hi,
VPLS provides the medium to for a E-LAN, and in Cisco implementations, the MAC learning is not actually done by a VPLS instance.
This can be best explained by an example.
PE(SW)-A ---- PE(SW)-B
PE(SW)-C
Now these three PE nodes under VPLS, are only provided the medium to connect to each other using P2P PW forming a full mesh.
For simplicity you can assume they are three switches connected in the above manner using copper. So this copper connecitivity is provided by VPLS.
And at the end of the day the end nodes learn mac addresses using the conventional method of flooding and learning. So you wont find any VPLS specific commands to see what mac address is the VPLS instance flooding. As its only providing a medium for connectivty. And the flooding is done by the end nodes. as they treat the VPLS VC as one of the outgoing port.

How to disable ipv6 address autoconfiguration ???

I am trying to disable ipv6 stateless address autoconfiguration to implement what this document describes:
http://docs.sun.com/app/docs/doc/816-4554/6maoq01o3?a=view
There are several problems though:
1)The manual says that something must be put inside the hostname6.xxx file but then goes on to give the command as it should be given from the command line instead of the content of the file. The manual should provide some form of exapmle content for the file.
2)I go to /etc/inet/ndpd.conf and put "ifdefault StatelessAddrConf false" inside, then I pkill -HUP in.ndpd and finally I issue ifconfig eri0 inet6 token fe80::c/10. However nothing happens. The interface address remains the one generated through autoconfiguration.
Could someone that has knowledge of this subject provide any help?
Thanks very much,
Thanasis

Hi,
I have a same problem, and think we didn't understand the documentation.
Here is the link of the ndpd.conf configuration page:
http://docs.sun.com/app/docs/doc/816-4554/6maoq01qt?a=view#ipv6-ref-10
I think this is the right sintax:
if
Sets per-interface parameters. Use the following syntax:
if interface [variable-value]
Table 11�3 /etc/inet/ndpd.conf Interface Configuration Variables
StatelessAddrConf
True
Controls whether the node configures its IPv6 address through stateless address autoconfiguration. If False is declared in ndpd.conf, then the address must be manually configured. For more information, refer to How to Configure a User-Specified IPv6 Token.
I think the variable is this: StatelessAddrConf
if-variable-name StatelessAddrConf false
I think: if StatelessAddrConf false
But I found the 'false' parameter with uppercase and lowercase letter.
(It is not working for me!)
And I found another configuration file, what is include the rules of the address (/usr/sbin/ipaddrsel ).
Here is the link:
http://docs.sun.com/app/docs/doc/816-5166/6mbb1kq56?a=view
Maybe, I found the solution.
http://docs.sun.com/app/docs/doc/816-4554/6maoq01qt?a=view#ipv6-ref-10
You can creat a logical interface, and you can set the IP address of this interface.
Example 11�6 Adding a Logical IPv6 Interface With the -addif Option of the ifconfig Command
The following form of the ifconfig command creates the hme0:3 logical interface:
// this is teh example, and it is not perfect on Sol10
# ifconfig hme0 inet6 addif up
Created new logical interface hme0:3
This form of ifconfig verifies the creation of the new interface:
# ifconfig hme0:3 inet6
hme0:3: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2
inet6 inet6 fe80::203:baff:fe11:b321/10
Here is my solution:
ifconfig e1000g0 inet6 addif 1234:0000:0000:0000:0200:50FF:FE09:B980/10
ifconfig e1000g0:1 inet6 up
# ifconfig -a6
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
inet6 ::1/128
e1000g0: flags=2000840<RUNNING,MULTICAST,IPv6> mtu 1500 index 2
inet6 fe80::20d:60ff:feee:aba8/10
ether 0:d:60:ee:ab:a8
e1000g0:1: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2
inet6 1234::200:50ff:fe09:b980/10
I have special IP address, but I don't know that it is working or not.
If you have any idea, please write!

How to set static IPv6 address/gateway in Arch (NOT tunnel)

Hey Everybody,
Today I decided to install Arch Linux. There was only one thing that I did not understand, and that is how to set up a static IPv6 address. I have native IPv6 connectivity at home and in Debian I used to edit /etc/network/interfaces to set up a static IPv6 adress. Since Arch uses rc.conf, what is the syntax to configure a static IPv6 address?
I used to add something like this in Debian in /etc/network/interfaces:
> iface eth0 inet6 static
> address *my static address*
> netmask 64
> gateway *my gateway address*
Or can I still use /etc/network/interfaces in Arch?
Thank you for help.

It can be done quite easily using the netcfg infrastructure.
/usr/lib/network/connections/ipv6static
#!/bin/bash
. /usr/lib/network/network
ipv6static_up() {
load_profile $1
ip -6 a a ${ADDRESS} dev ${INTERFACE}
if ! [ -z "${GATEWAY}" ]
then
ip -6 r a 2000::/3 via ${GATEWAY} dev ${INTERFACE}
fi
ipv6static_down() {
load_profile $1
ip -6 a d ${ADDRESS} dev ${INTERFACE}
if ! [ -z "${GATEWAY}" ]
then
ip -6 r d 2000::/3 via ${GATEWAY} dev ${INTERFACE}
fi
ipv6static_$1 $2
exit $?
/etc/network.d/eth0static
CONNECTION="ipv6static"
DESCRIPTION="Static configuration for IPv6"
ADDRESS="2001:dead:beef:cafe::1/64"
INTERFACE="eth0"
GATEWAY="2001:feed:dead:beef::1" # Comment this out if no route needed
I haven't tested the gateway part, but I don't see why it wouldn't work. You'll need iproute2, and to read up on netcfg (see http://wiki.archlinux.org/index.php/Network_Profiles) if you have trouble.
